5 Signs Your Laptop Battery Needs Replacement (And What It Costs)
Laptop batteries degrade gradually, which makes it easy to ignore the early signs until the laptop is suddenly unusable unplugged. Here's what actually indicates a failing battery — and when it's worth replacing versus just recalibrating.
The 5 signs
1. The laptop dies immediately when unplugged, even showing 20-30% charge — a near-certain sign the battery can no longer hold charge reliably.
2. Charging stalls at a fixed percentage (often 80-95%) and never reaches 100%.
3. The laptop's base feels unusually warm or you notice any bulging near the battery compartment — this is a safety issue, stop using it immediately.
4. Battery percentage jumps erratically (e.g. 40% to 15% in seconds) rather than draining smoothly.
5. The laptop is 2+ years old with daily heavy use — batteries are consumable parts, and degradation at this point is simply normal wear, not a defect.
What replacement costs
Battery replacement for most mainstream brands (Dell, HP, Lenovo, Asus, Acer) starts at ₹1,799, done on-site in under 30 minutes. MacBook and ultrabook batteries (often glued/sealed units rather than swappable cells) typically cost more due to the more involved disassembly and part cost.
